' Original application filed January 17, 1910, Serial No. 538,519.Divided and this application filed February 4, 1911. Serial No. 606,499.

To all whom it may concern:

Be it known that we, MICHAEL Woons, a-

tralia, and THOMAS JEFFERSON GILBERT, a

subject of the King of Great Britain and Ireland, and residing at 1Minnie street, Brunswick, in the countyof Bourke, State of Victoria,Commonwealth of Australia,

have invented certain new and useful Improvements in and Relating toMachines for Dressing Rails,-of which the following is a specification.

This invention relates to machines for dressing rails of the kind inwhich the dressing means are carried by an attachment which is pivotallysecured to the machine as described, for example, in the specificationto our copending application Serial No. 538519 filed January 17th 1910.The-object of the present invention is to provide an efiicient andreadily attachable combined carriage and holder for a tool or toolsadapted for use in removing the burs and bevels which occur at the bendsor curves in a track having plain headed rails, and also to cut out newand true beds in the rails to permit'of the renewal of the fish plates.

The invention consists m a combined carriage and tool holder for usewith rail dressing machines adapted to support vertical millin means andto be removably pivoted to t e machine about a central longitudinal axisthereof,

One mode of carrylng out the invention the accompanying drawings Figure1 is an elevation of a combined carriage. andholder constructed inaccordance with the present invention, and Fig. 2 is a plan view of thesame. Fig. 3 is an end elevation of Fig. 1. Fig. 1 is a sectional.

elevation of a detail.

In all the figures parts have been omitted sectioned or broken away, forthe sake of clearness.

In carrying out the invention according to one mode, thecombined'carria-ge and holder consisting of a framework (1V is providedwith removable trunnion caps b for accommodating hollow trunnions on therail dressing machine, thus permitting of the carriagebeing removed whennecessary. The framework a is supported on both sides by flanged wheels0 each of which is mounted on a pin a? secured to or formed integralwith a slide e attached to a screw f engaging with a worm wheel nut gwhich can be rotated by means of a worm h operated by ahand wheel 2' sothat, on turning the hand wheel i the flanged wheel is raised orlowered. A removable adjusting piece j may be interposed between theframework a and the slide e for regulating the distance between thewheels so as to suit any gage of I rails.

Secured to the framework is an upper cross bar 70 and a lower cross barZ upon which is supported at either end a laterally adjustable bracket mthrough which passes a vertical spindle ncarrying at its lower end amilling tool 0 which receives its motion from any suitable motor carriedby the rail dressing machine, the arrangement of the gearing being asfollows :The shaft 1 which passes through the hollow trunnions' of theraildressing machine, is connected at one end to a motor driven shaft byany suitable coupling, and carries at its other end a bevel wheel 9engaging with one of two bevel wheels 17 slidably mounted on a shaft 8upon each end of which is a toothed pinion t engaging with a toothedwheel 24 carried by a shaft '1) which is journaled in.

a bearing v, extending from the bracket m and carrles a bevel wheel wengaging with a bevel wheel 00 mounted on the spindle n. The bevelwheels 1" are engaged or disengaged with the bevel wheel 9 in anyordinary way, thus affording a convenient means of reversing thedirection of rotation of the cutter.

In order to provide means for adjusting the milling tools in a, verticaldirection, each spindle a (see Fig. 4) is provided at- The spindle n isprovided with a screw thread y engaging with a toothed wheel nut 2 whichengages with a toothed pinion 1 carried on a spindle 2 operated by ahand wheel 8. On turning the hand wheel 3 the spindle 12, is raised orlowered thus adjusting the tool.

Each bracket m is adapted to slide laterally upon the cross bars 76 andZ and is se cured thereto by means of flanges 4 and bolts 9, thenecessary adjustment being effected by means of a hand wheel 5 operatinga screw 6 which turns within a nut 7 in the framework 44 and moves thebracket m by means of a collar 8 the shaft 7; being adapted to slidethrough the wheel at so as to keep the bevel wheels to and as always inmesh.

lVhen burs and bevels are being treated in plain headed rails aliningand steadying devices are used. This consists of a bracket 17 attachedto the framework a and carrying a roller 11 which makes contact with theinner side of the rail head. Pivoted at 12 is a bell crank lever havinga long spring arm 13 and a short arm 14;, the former of which can beadjusted by means of a screw 15, while the latter carries a roller 16which, by means of the adjusting screw can be brought into contact withthe outer side of the rail head.

The tools may treat either side of their respective rails to remodel thehead thereof, or by using suitable tools new fish plate beds may be cutout accurately and speedily.
